Abstract (en)
[origin: WO2010040495A2] The invention relates to a method for desulphurization, wherein a gas mixture, for separation of acid gas components, is subjected to a separation process in which an acid gas containing carbon dioxide and sulphur compounds, in particular hydrogen sulphide, is formed, wherein the acid gas, for separating off elemental sulphur, is fed to a Claus plant and wherein the residual gas leaving the Claus plant is subjected to further fractionation in which the water formed in the Claus process is at least partially removed. According to the invention, as oxygen-containing reaction gas, only technically pure oxygen is fed to the Claus plant, wherein carbon dioxide stored downstream of the Claus plant is taken off in a purity which enables immediate sequestration or industrial use.
